Description Maciej Pawlik 2007-11-17 15:41:10 UTC
When using blender-2.45 with ffmpeg flag, and most recent ffmpeg-0.4.9_p20070616-r2, adding any *.avi file as an input for texture (or source in 'sequence') results in corrupted image (attatchments).

Reproducible: Always

Steps to Reproduce:
1. emerge =blender-2.45
2. emerge =media-video/ffmpeg-0.4.9_p20070616-r2
3. add .avi file as texture source
Actual Results:  
Corrupted image instead of actual movie.

Last working configuration (and workaround):
media-video/ffmpeg-0.4.9_p20070616 (no swscaler)

and modified blender-2.45:

-       epatch ${FILESDIR}/blender-2.44-swscale.patch
        if use ffmpeg ; then
                cd ${S}/extern

I think, that this swscale patch is not taking care of input, because output to ffmeg works fine.

that's annoying, instruct me on how to reproduce the issue please.

Start blender, choose "4-sequence" window sheme (center-top list), and move mouse cursor to middle window. Then press space, and click "movie", choose a file, place it somewhere in the window, then move the time slider over the clip and observe the results in preview (black window on top right, middle mouse pans the view).

Fixed patch.

Ok, found it!:)

There was an error in old version of this patch. In ffmpeg_fetchibuf() pixel formats were in wrong order. I've noticed it while comparing new code to the old commented-out.
